Crownʼs new CTs series of power amplifiers are remarkable for their loud, punchy sound; sustained, tight bass; and superior protection against overheating and overload. This paper explains the design features behind those advantages. After reading this information, youʼll know why Crown CTs amps sound better than the competition. CTs amplifiers can provide large amounts of power into various loads, such as 2, 4, 8 ohms and 70V. With most power amps, the maximum output power tends to drop as the load impedance increases. But with the CTs series, the power stays the same at almost any impedance. 2-ohm Dual (per Ch.) 250W 4-ohm Dual (per Ch.) 600W 8-ohm Dual (per Ch.) 600W 16-ohm Dual (per Ch.) 300W 70V Dual (per Ch.) 600W 4-ohm Bridge 500W 8-ohm Bridge 1200W 16-ohm Bridge 1200W 140V Bridge 1200W Crown switching power supply for less weight Sustained Power on long-duration signals due to regulated, "stiff” power supplies with incredible energy storage (huge filter capacitors). Extra Hidden Power during high-level transients and during incomplete use of all the channels. Overheating and overload protection thanks to the sophisticated TLC circuitry which compresses the signal only when needed. Compression is controlled not by temperature, but by signal voltage. This keeps the loudness up during compression more than with competitive amps.

• 24 bits/192 kHz 256x Oversampling Converters.
• Output Delay: 0 to 7.1 meters (20.69ms) per channel.
• XOver: Up to 48dB/oct Butterworth, Linkwitz-Riley and Bessel.
• EQ: 9 filters per channel (Parametric, Shelving, LP,HP,BP,SB).
• Gain, Mute and Phase inversion per channel.
• RMS Power and Peak Voltage output limiter per channel.
• Real Time operation from USB or front panel configuration.
